What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

 Transparency and The Dome.
Existing technology has largely solved a major problem of speaker design through the use of the acoustic suspension driver; extended frequency response.  Today, what's missing from most sound in most people's living rooms is something a touch more suble.  It's called transparency.
The hemispheric dome tweeter allows a wider dispersion of high frequencies.
But the dome's own material weight causes it to lag behind the input signal. It simply doesn't respond fast enough, creating an opaque, masked sound that lacks fine detail and definition.  The ideal dome material for midrange and high frequency drivers would be extremely rigid and, most importantly, virtually weightless.

Introducing the Beryllium Dome.
Why did it take so long?  After all, beryllium is the lightest, and most rigid metal known, and has a sound propagation velocity twice that of commonly used aluminum.
Beryllium is lighter and stronger and propagates sound better than other metals.
But because of beryllium's inherent characteristics, it resisted attempts by any manufacturer to form it into a diaphragm, let alone a dome.  Until now.
The new Yamaha Beryllium Dome, formed by Yamaha's unique vacuum deposition process, is lighter than any other speaker diaphragm found today. So it's more responsive to direction changes in amplitude and frequency of the input signal.  This is called transparency. It can be noticed best in complex musical passages and can be best described as highly defined and finely detailed.  Only Yamaha has it.
 Midrange - The Voice of Your Speaker.
It's no secret that between 500 Hz and 6 kHz is where most audible differences in speakers occur.  It's where we hear the human voice, and it is the hardest part of the frequency spectrum to reproduce accurately.
Once again, berylium solves the problem of uneven response. Since it's so lightweight the dome can be made larger and lighter than before possible for a midrange driver. It extends the linear portion of its response curve.
The midrange driver's frequency response is so wide that we can select only the choice flat section of its frequency response, thereby eliminating the peaks and valleys most competitors are forced to use.
The beryllium Dome creates simply the flattest response; least colored, most natural sounding midrange of any speaker around.  Carefully designed acoustic equlizers flatten the frequency response curve further.
The NS-1000M Monitor is so accurate that you may even hear enhanced detail in a recording you once thought already perfect.

Re-thinking the Woofer.
Some respected speaker manufacturers buy their low frequency drivers wholesale.  Yamaha doesn't buy them. We make them.
Even the very cone material itself was researched and developed and manufactured specially by Yamaha. (Its' made much more dense than most cones. That means a tighter cleaner sound.) And the frame is cast in our own foundry so we can control quality.
A plucked string of a bass sounds like a plucked string bass note. Instead of a dull thud.
 The Tangential Edge and Other Extras.
Yamaha designed a special suspension system that holds the beryllium dome to the speaker frame with less contact allowing it to move more freely. It's called the Tangential Edge. (you may not hear the difference at first, but you will.)
The crossover system was specially designed to have  a very low DC resistance, increasing the system efficiency.
Most highly accurate systems need a large amp to drive them properly. The NS-1000M Monitor requires only 15 watts RMS to fill an average room with loud music, yet can handle RMS power output exceeding 100 watts.

By Our own skilled Hands.
Yamaha's philosphy is one of self-reliance.
That's why, for example, we build the critical speaker components ( like cone materials and speaker baskets) rather than purchase them.  That includes the speaker enclosure made from material designed for anti-resonance characteristics. (our piano making experience was essential here.)  There are enough speaker system modifications and copies around already.  This is something original.

Proudly presenting the NS-1000M.
It's not inexpensive or easy to find.  The NS-1000M is sold as right and left-hand units, and by the pair only.
Yamaha is making them as fast as we can,but you may have to wait a short while until your Yamaha Audio Dealer has a pair for you to audition. (he also features Yamaha speaker s based on the same techno;logy and quality at less money.)  pateince, please.

Part of the Yamaha system.
The NS-1000M Monitor is the ultimate air suspension speaker system.  That is a strong claim to make. In the future, Yamaha will present the ultimate power amplifier, tuner, preamplifier and turntable.
Actually advancing the state-of-the-art. Of the major components of a music reproduction system.
In short, the ultimate system.  We're convinced that no matter what you think is the best today, we'll make you dissatisfied with it. Don't say we didn't warn you.
